XP2U梅特勒XP2U微量天平
The METTLER TOLEDO XP2U is an innovative ultra-microbalance, providing optimal weighing performance, user friendliness and quality standards. The XP2U ultra-microbalance has a very high resolution: 21 million digits. A brilliant colored touch screen display, customized screen programming, inligent user guidance, and hands-free infrared draft shield control make this highly-precise balance faster, easier and more efficient than ever before.
METTLER TOLEDO XP6 microbalance and XP2U / XP6U ultra microbalance are designed to boost efficiency, reliability and supports network compatibility.

1)According to OIML R76
2)In the temperature range 10…30°C
3)Stability of sensitivity as from first installation with FACT
4)Can be used for the estimation of uncertainty sd: standard deviation Rgr: gross weight Rnt: net weight (sample weight) a: year (annum)
*Repeatability and minimum weight can be improved and affected by the following measures: - choice of suitable weighing parameters, - moving to better location, - using smaller tare containers
